You would actually benefit much more by going to Blender's or Wings 3D's forums and posting for help there. We can only tell you what you need to do for Paintball 2, we can't teach you the art of 3D modeling. As for "is there any models" yes, there are some in production, to be released soon*. However, I wouldn't recommend making any models to put into the game until you've spent a few months practicing 3D modeling and have followed lots of tutorials.
